Salvelinus fontinalis Female Maximum GSI value Maturity indices were higher at 19 and 21 C since these fish did not spawn. The decoded-mean-maturity index (8.6) for female brook tout at 19C was derived from only three fish (0.5, 15.6, and 17.7) on November 7 the female maturity indices were 19.7 at 19°C and 16.2 at 21°C 19.0 percent
